ADZ FINISH ORNAMENTAL WOODWORKING MACHINE Filed March 9, 1928 IN VEN TOR.

ATTORNEY Patented June .3, 1930 UNITED STATES PATENT OFFICE GEORGE P. DRISKELL, OF SAN DIEGO, CALIFORNIA .ADZ-FINISH Oman-Emir Application filed March 9,

My invention relates to a machine for providing an adz finish to wood surfaces and the objects of my invention are: first, to provide a machine for finishing wood surfaces so that they have the appearance of an adz finish; second, to provide a machine of this class which will reproduce the ordinary adz finish to wood surfacesin symmetrical or nonsymmetrical form as desired; third, to provide a machine of this class the cutting of which is done by an electrical power machine; fourth,'to provide a machine of this class which is adjustable for different width beams or members to be adzed; fifth, to provide a 1 machine of this class which may be operated whilethe operator is inseated or standing posture as desired; sixth, to provide a novel cutter for machines of this class, and seventh, to provide a machine of this class which is very simple and economical of construction, efficient, easy to operate and which will not readily deteriorateor get out of order.

With these and other objects in view as will appear hereinafter, myflinvention consists of 95 certain novel featuresof construction, combination and arrangement of parts and por tions as will be hereinafter described in detail and particularly set forth in the appended claims, reference being had to the accompany- 0 ing drawings and to the characters of ref erence thereon which form a part of this a'pplicationin which:

Figure 1 is a sideelevational view of my machine shown positioned upon a piece of wood to be provided with an adzedfinish on itsfupper surface; Fig. 2 is a top or plan view thereof; Fig. 3 is a transverse sectional view through 33 of Fig-2 andshowing by dotted lines an adjusted position of the guide members; Fig, i is an enlarged side elevational view of the cutting device, and Fig. 5'is aside elevational viewat right angles thereto.

Similar characters of reference refer to similar parts and portions throughout the several views of the drawings.

The main side members 1 and 2, adj ust-able supports 3 and 4:, roller 5, adjustable guides 6 and 7 weight 8, gage member 9, electrical drill-motor l0, clamp member 11, motor supwoonwonxrne MACHINE 1928. Serial No. 250,328.

porting plate 12, cutter 13 and handle members 1 1 constitute the principal parts and portions of my adz finishing machine;

The side members 1 and. 2 are relatively broad and at their front ends are provided with slots 1 and 2 respectively in their outer side surfaces adapted to receive the supporting members 3 and.& and these members are held in adjusted relation on the members 1 and 2 by means of thumb screws 1 and 1, thus providing'means for raising and lowering the frame composed of the members 1 and 2 and the cross bars. It will be noted that these members 1 and 2 are spaced apart by means of cross bars 15 and 16 and are positioned so that they are spaced relatively close together at their front ends and a greater distance apart at their rear ends. Rev-olubly mounted in the lower end of the supports 3 and 4 is a roller 5 which is adapted to rest uponthe upper surface of the material to be finished. Positioned between the supports 3 and lis a cross bar 17 upon which is shiftably mounted a pair of adjustable guide members 6 and 7 which are provided with slots 6 and 7 in which are mounted wing screws 6" and 7 and it will be noted that these members overlap each other and are adapted to be clamped by means of the wing screws 6 and 7 for holding the members 6 and 7 in certain relative spaced relation to each other, thus providing adjustable guides for varying width members. Positioned on the inner surfaces of the guide members 6 and 7 at their lower ends are roller members 6 and 7 c which are adapted to reduce the friction against the side surfaces of the timbers. Shiftably mounted in the outer surfaces of the members 1 and 2 positioned in grooves 1 and1 is a 'U-shaped gage member 9, the lower side of which is adapted to rest on the timber to be finished when the desired depth of out has been made. The upwardly extending portions of the members 9 are adjustably mounted in these grooves and clamped in position by means of screws 9 having wing heads. Supported on the members 1 and 2 and positioned between the cross members 15 and 16 is a weight 8 preferably of cast iron or cement which is adapted to provide sufficient weight on the machine to hold it down in proper position while operating. Positioned between the members 1 and 2, back of the member 16, is a plate 12 provided with a central hole therein and mounted on the upper surface around said hole is a clamp member 11 which is of the proper size to fit around the base portion of a conventional electric drill, as shown by 10, which is supported on the plate 12 and held securely by means of the clamp member 11. The driven portion of said drill extends downwardly and secured on the lower end thereof is a laterally offset relative to the axis of the drill cutter head 13 which is preferably metallic and provided with a slot 13 therein in which is adapted to be mounted a cutter member 13". Slightly spaced from this cutter member 13" in the member 13 is a slot 13 which is provided with an enlarged port-ion into which is fitted a tapered pin 13 and in the upper portion of the slot 13 is a tapered rectangularly shaped key 13 It will Y be noted that the cutter member 13 is of considerable length and is adapted to be positioned on an angle and substantially to one side of the drill axis, as shown best in Fig. 5 of the drawings, and may be positioned on varying angles and adjusted by means of the key 13 and'is held in position by means of the metal between the members 15" and. 13 and adapted to be shifted by driving the metal pin 13 into position, all as shown best in Figs. 4 and 5 of the drawings. It will be here noted that the particular shape of the cutter shown in Figs. 4 and 5 with the one end lower than the other provides when revolved a concave surface which when shifted simulates an adz cut. The rearwardly extending ends of the members 1 and 2 are provided with downwardly turned handle portions 1. Adjustably mounted on the sides of the members 1 and 2 just back of the cutter member is a handle consisting of the members 14 with cross members 14 and 14". These members 14 are supported by means of wing screws the upper ones of which are mounted in slots in the members 14, thus providing for shifting the handle member consisting of the members 14 and 14 to various angular positions relative to the members -1 and 2. It will be here noted that the handle members 1 are to be used when the operator is positioned in a sitting posture while the others are to be used when in a standing posture.

The operation of the machine is as follows:

The machine is positioned on the timber, as shown best in Figs. 1, 2 and 3 of the drawings. The guide member 9 is adjusted to provide for cutting the proper depth adz finish in the upper surface of the timber. The operator then starts the electric motor 10 and supports the rear end of the machine by either the handles 1 or 14 and lets the cutter member down onto the upper surface of the wood in the varying positions desired. The gage 9 prevents the cutter from cutting too deep and the operator shifts the cutter head to varying positions on the upper sur face of the wood and moves it along on the roller 5. The cutter member l5 thus provides finished adz surface to the upper surface of the timber.
